The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Hydrodynamic interactions in semi-dilute colloidal rod suspensions under shear are not negligible and drive a cascade of tumbling events that disrupts flow alignment and increases viscosity and normal stress differences.

C2weakest assumption

The particle-based simulations accurately capture the long-range hydrodynamic interactions without significant numerical artifacts or approximations that would alter the observed cascade behavior at the reported shear rates and concentrations.

C3one line summary

Hydrodynamic coupling in sheared colloidal rod suspensions drives a tumbling cascade that disrupts alignment and increases viscosity and normal stresses.
